Barty served one more ace than her opponent — 8-7 — but also had six double faults, compared to just two for Goerges.

Barty won her only previous match against Wang in Strasbourg earlier this year.

Wang served seven aces and converted five of seven break points against the overmatched Muguruza to become the first Chinese player to reach the final of the tournament.

Wang was a late replacement for original group-stage winner Madison Keys after the American withdrew from the semifinal with a left knee injury.

The tournament in Zhuhai features the leading players on the women’s tour who didn’t qualify for the WTA Finals in Singapore last week. The 12-player draw is divided into four groups, with the winner of each group advancing to the semifinals.
